Q

What are the 5 basic parts of an aircraft?

A

Powerplant, Wind, Fuselage, Empennage, Landing Gear

2
Q

What are fuselage structure types?

A

Truss, Monocoque, Semi-monocoque

3
Q

What are the 2 types of truss construction?

A

Open truss and closed truss

4
Q

What is the difference between open truss and closed truss?

A

Open truss the struts and wire bracing are visible, closed truss the structure is covered with fabric or metal to streamline the airplane

5
Q

When the skin is designed to be the only load carrying structure it is a _______ design.

A

Monocoque

6
Q

Load carrying skin with an additional substructure for added strength is a ______ design

A

Semi-monocoque

7
Q

Monocoque designs use ________ to support almost all the load

A

Stressed skin

8
Q

Though very strong, a problem with stressed skin is that:

A

It will collapse easily if dented

9
Q

The empennage consists of the:

A

Vertical stabilizer and horizontal stabilizer

10
Q

Where is the rudder located?

A

On the vertical stabilizer

11
Q

What is a stabilator?

A

A one piece stabilizer/elevator

12
Q

What does the vertical stabilizer do?

A

Helps maintain a straight path through the air

13
Q

What does the horizontal stabilizer do?

A

Provides stability and balance by producing a tail down force

14
Q

What does the rudder do?

A

Moves the nose left and right (yaw)

15
Q

How is the rudder controlled?

A

Foot pedals

16
Q

Pushing the rudder pedal to the right will move the rudder _____, moving the tail to the ____ and the nose to the ______

A

Right, left, right

17
Q

What is the elevator used for?

A

To pitch the nose up and down

18
Q

Wings are designed to have ____

A

The maximum lifting capability possible

19
Q

Where are the ailerons located?

A

The trailing edge of the wing, from the midpoint of the wing to the wingtips

20
Q

Turning the control column to the left, the left aileron is deflected ____ and the right aileron is deflected _____

A

Up, down

21
Q

In most small aircraft, flaps are ______ controlled

A

Electrically

22
Q

Flaps are:

A

Lift altering devices used for takeoff and landing

23
Q

Flaps extend from the _____ to the _____ of the wings

A

Root, midpoint

24
Q

If the third gear is under the tail, the plane has a ______ configuration

A

Conventional

25
Q

With tricycle gear, the third gear is located _____

A

Under the nose

26
Q

An oleo strut absorbs pressure _____ then releases it _______

A

Rapidly, slowly

27
Q

For most light aircraft, an oleo strut is used on the ________ only.

A

Nosewheel

28
Q

The nosewheel absorbs most of the shock because:

A

The weight of the powerplant is directly above it

29
Q

Disc brakes are located on the _____ but not the ______

A

Main wheels, nose wheel

30
Q

Differential braking can be used to _____ but only when necessary.

A

Turn the plane on the ground

31
Q

On which of Newton’s laws does a turbine engine operate?

A

Third – For every action there is an equal and opposite reaction

32
Q

What are the three axes of flight?

A

Vertical - Yaw, Lateral - Pitch, Longitudinal - Roll

33
Q

What are the three primary control surfaces?

A

Rudder, elevator, ailerons

34
Q

Archimedes discovered that pressure ____ with depth

A

Increases

35
Q

Archimedes principle states:

A

Any object, wholly are partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object

36
Q

Air density _____ as altitude increases.

A

Decreases

37
Q

Why won’t a balloon continue to rise forever?

A

As it rises, air density decreases and therefore so does buoyant force

38
Q

What is the difference between an airship and a balloon?

A

An airship has a form of propulsion
